The teacher ought to possess the control of the content, the communication and the relationship as the key elements of the learning process. Among these elements, the relationship between teacher and student becomes one of the main ones. Other elements are: the mutual respect of the teacher and the student; the trust that the student must have in his/ her teacher; the student’s commitment to following the instructions of the teacher; the teacher’s interest on the student’s learning; the follow-up and the careful examination of the progress of the student by the teacher. The relationship involves, therefore, a bond, evidencing the concept of trust. Trust is both important and dangerous, once it involves the risk of the person who trusts someone be disappointed, the risk of loss and damage, including self-esteem. The relationships based on trust requires that both parties be disclosed, so that there will be no doubts about the good faith involved in this relationship. The appraisal that the teacher conducts using subjective tests is essentially based on trust; on the other hand, the student cannot breach the principle of trust by cheating. "The Emperor's Club" shows the relationship between teacher and student, and that the principle of trust may also be valid in practice.
